| 1 | Cell adhesive spectra along surface wettability gradient from superhydrophilicity to superhydrophobicity显示文摘Surface wettability is important to design biointerfaces and functional biomaterials in various biological applications. However,to date, it remains some confusions about how cells would response to the surfaces with different wettabilities. Herein,we systematically explore the adhesive spectra of cells to the surface with wettability gradient from superhydrophilicity to superhydrophobicity, clarifying the effect of wettability on cell adhesion. We envision that this study may provide valuable information for the design of biomedical implants with controllable cell adhesion, such as neural interface devices and flexible implant. | Jingxin Meng Gao Yang Lu Liu Yongyang Song Lei Jiang Shutao Wang | 2017 | Science China Chemistry2017，60，5： | 4 |

| 4 | Flexible Dry Hydrogel with Lamella-Like Structure Engineered via Dehydration in Poor Solvent显示文摘Hydrogels are among the most promising biologic materials in recent technology with numerous desired applications,including serving as biosensors,drug delivery vehicles,and tissue-engineered products for cell matrices.However,they often dehydrate,and become stiff and brittle in air,causing loss of flexibility and functions.Several layered structures have been proven to increase the strength,toughness,and even flexibility of these materials,which might provide a new clue for the sustenance of the flexibility of drying gels.Herein,we report a novel solvent-dehydrated hydrogel engineering approach,aimed to change the inner structure and keep the flexibility of a dehydrated hydrogel in the air via solvent-induced dehydration,for example,acetonedehydrated polyacrylic acid hydrogel.This flexible dry gel could be folded,twisted,and stretched without any damage due to the assumed lamella-like structures,contrary to dry gels without these microstructures or those with porous structures,which retain brittle consistency.The flexible dry gel also exhibited excellent self-healing capability with the assistance of solvents.Fascinatingly,this flexible gel film displayed strain-visualizing paper writing/erasing performance properties,with water acting as invisible ink.Thus,this fabricated flexible hydrogel film might function as confidential information storage material.Our current approach is versatile,hence applicable to other hydrogels,and provides insight into the engineering of other functional gels for extended future applications. | Feilong Zhang Jiajia Zhou Zhen Gu Man Yang Siheng Li Yongyang Song Jun-Bing Fan Jingxin Meng Peiyi Wu Lei Jiang Shutao Wang | 2020 | CCS Chemistry2020，2，1： | 0 |
| 5 | Building block copolymer particles via self‐assembly within a droplet显示文摘The self‐assembly of block copolymers(BCPs)within emulsion droplets is a flexible strategy for the preparation of polymer particles.This strategy permits the finetuning of shapes,internal structures,and surface nanostructures of the polymer particles,thus allowing many applications.Although some literature has reviewed the BCP preparation via self‐assembly within a droplet,a comprehensive summary including in‐depth understanding,controllable preparation,and application is lacked.In this review,we systematically delve into the multiple mechanisms that drive BCP self‐assembly within emulsion droplets,such as commensurability effects for minimizing total free energy,interfacial instability,organized spontaneous emulsification,phase separation of multiple components,and entropy effects between BCPs and nanoparticles.Additionally,a strategy combining selective cross‐linking and disassembly can further generate Janus particles featuring unique structures.Next,various applications across multiple disciplines are discussed,including drug delivery,display,biomedical imaging,macromolecular separation,and fuel cells.Finally,we present an overview of the current challenges and future directions for BCP emulsion self‐assembly,covering mechanism investigation,molecular design,stability control,and application exploration.We anticipate deeper understanding,more varieties,enhanced performance,and broader applications can be achieved with BCP emulsion self‐assembly after addressing the challenge. | Sen Zhang Han Bao Xinyi Shen Yongyang Song Shutao Wang | 2023 | Droplet2023，2，4： | 0 |
